Application filed October 1?, i924. Serial No. 744,270.

To all whom it may concern Be it known that 1, JOHN J. HALLIHAN, a citizen of the United States. residing at Chartley, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Collar Buttons. 01" which the following is a specification.

This invention relates to an improved construction of button such as a collar button, stud button, and the like; and has for its object to provide a button of this character having a metallic head and shank portion and a non-metallic base member to which the metallic portion is securely connected.

A further object of this invention is the provision of an inner, tubular, connecting member bound, flxed or locked in the shank portion of the button member and having a flange portion which is secured to the non metallic base member to connect the base member to the head portion of the button.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings Figure 1 is a sectional elevation showing details of construction of my improved button.

Figure 2 is a sectional elevation of the thimble member which is partially drawn up from sheet stock.

Figure 3 is a detail of the inner tubular connector member in section.

Figure 4: shows this inner connecting member as positioned in the outer thimble member ready for both to be swaged into shape.

Figure 5 shows the shank portion of the button as having been swaged or reduced in diameter leaving a hollow head member with a base flange, and showing the flare in this head taken by the inner connecting member when so swaged. whereby it is firmly locked in the shank of the button.

Figure 6 is a sectional elevation showing the non-metallic base member of the button with the undercut recess therein.

Figure 7 is a top view of this base member.

It is found in the practical construction of buttons of this character inwhic-h the head and shank portions of metal are con nected to a non-metallic base member by swaging and spreading the base flange of the button into a recess in the base member, that unusual prying strains when brought to bear upon such a button often result in the separation of the base portion from the shankportion, and to obviate this difliculty i have formed a base flange on the metallic portion of the button to set against the inner face of the base, and I have provided an inn r connector member which is locked in the shank of the Lrutton, when the shank is subjected to the reducing or swaging operation. and this inner. connecting member is provided with a flange of a diameter less than that of the shank flange and when swaged or spread into engagement with the undercut walls of the non-metallic base member the two are so flrmly connected together that they cannot be separated by any strain to which they are ordinarily subjected; and the following is detailed description of the present embodimentof my invention showing one means by which these advantageous results may be obtained With reference to the drawings, my improved button is formed with a hollow head portion 10, a reduced shank portion 11 and a flange portion 12, all of which are formed from sheet stock first drawn up into thimble shape 13, as illustrated in Figure 2; and in order to firmly secure this metallic button member to a non-metallic base member 14, which is usually made of pearl, I provide a recess 15 in one face of the base member, the recess having undercut peripheral side walls 16 and in order to firmly secure this metallic button member to the non-metallic base, I have inserted into the thimble mem ber 13 a tubular member 17 which, when the neck portion 11 of the thimble member, is reduced into the form illustrated in Figure 5, this connector member is also reduced at its middle portion providing an enlarged, upper, flaring flange 18 which extends into the hollow head 10 of the button, and at the same time forms a downwardly extending flange portion 19 extending from the lower end of the button member below the flange portion thereof. Thus it will be seen that in order to connect the metallic head and shank portion of the button to the nonmetallic base portion, I place the flange portion 19 into the undercut recess 15 of the base member and by applying pressure to both, this flange portion 19 is caused to spread so that its edge firmly engages the undercut walls of the recess thereby securely locking the metallic portion thereof; and the flange 12 of the neck portion serves as a broad or extended bearing about the recessed portion of the base to support the same and resist a prying action between the head portion and the base portion of the button greatly strengthening the connection between the two.

My improved button is very simple and practical in construction, is very strong and durable and its great strength enables it to resist unusual strains and materially lengthens its operating life.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention-being defined and limited only by the terms of the appended claims.

I claim:

1. A button having a hollow head portion, a reduced shank portion and a base flange, all formed of a single integral piece of metal, a non-metallic base member engaging said flange, and an auxiliary connector member housed in said button shank by which the metallic portion of the button is connected to the non-metallic base member thereof.

2. A button comprising a non-metallic base member having an undercut recess in its face, a metallic shank member enlarged its outer end to form a head portion and having a flanged portion for engagement with the face of said base member, and a connector member within said shank flared to grip the wall of said undercut recess and engaging portions of said shank for securaid members together.

A button having a hollow head portion, a reduced shank portion and a base flange, a non-metallic base member having an undercut recess in its face, and an auxiliary tubular member fixed in said shank and having a flange of a diameter smaller than that of said shank and spread into said undercut recess in the base member to secure said base in position against the larger shank flange. 4i. A button having a non-metallic base member with an undercut recess in its face, a hollow head portion having a shank with an enlarged flange adapted to cover said recess in the base and rest upon its face, and an inner tubular member fixed in said shank and having a flange engaging the walls of said undercut recess to secure the head portion to the base portion of the button.

5. A button comprising a non-metallic base member having a recess in its face with its bounding walls undercut, a hollow metallic shank member having an enlarged head and a base face engaging flange, and a connector member housed in said hollow shank and having one end flaring to engage said undercut walls and its other end flared to engage portions of said enlarged head whereby said base and shank members are immovably secured together.

In testimony whereof I affix my signature.
